The example of pick-up member is shown and described, and the pick-up member can also be constructed in substantially different modes.
Similarly, reverse end of tubular needle weaves before toe closing and if necessary after toe closing
The component of product can be different from those of exemplified explanation component herein.
The structure of locking device 41 can be with the difference as example exemplified explanation herein.Importantly, the dress
It sets and constitutes connection tissue in the intermediate region on sinker loop that is, between adjacent pick-up member, have benefited from there may be used
Obtained bigger space, and do not need the accurate mechanical engagement between the needle 43 of locking device 41 and pick-up member.
In certain embodiments, method of the invention provides certain rows that make at least the last one row or last
Coil is not running.In this way, when pick device 23A, 23B obtain coil MA from needle and pass tubular knitted article from syringe
When being handed to locking device 41, and when the tissue of half of row is overturn to other half of row, running is not present in product
Risk.The production of the tissue of the row of not running is known and does not need specifically to illustrate in the prior art.
For example, US 3046768, US 5426957, US 5115650, US 2379649, US 3430462, US 3751942, US
3470715, the publicly available example to form the method, apparatus and technology of the row of not running of US 4005589.US
A kind of 5992182 open particularly effective methods that can be used in the method for the invention.The content of above mentioned patent
It is incorporated into this specification.
Moreover, in certain embodiments, it can be with for exampleElastomeric yarn constitute last one or more cross
